How to Use Mineral Drops for RO Water

The concept is simple: a small bottle of concentrated minerals that you add directly to your glass.
No installation.
The Minerals That Matter
The core ingredients in a good mineral drop formulation are calcium and magnesium, the two minerals reverse osmosis removes almost entirely.
Calcium and magnesium are the minerals most responsible for how water tastes and feels.
A calcium to magnesium ratio of 2:1 or 3:1 is what most quality formulations target.
Dosing Mineral Drops for RO Water
Dosing instructions vary by brand, but most recommend between 20 and 40 drops per litre of RO water.
Drops dissolve almost instantly in RO water, so no stirring is required.
Since you are dosing by hand, the mineral level will vary slightly from glass to glass.
When Drops Make Sense
They also travel well, which makes them a practical choice for people who use RO water at home and want consistency when they are away.
For larger households drinking four or more litres a day, the per-serving dosing routine becomes tedious.
At roughly $0.10 per litre, drops are not the cheapest method at high volume but are accessible as a starting point.
A Quick Checklist Before You Buy
Not all formulations are equal, and a few quick checks separate quality products from weak ones.
Third, look for a product that states expected TDS output per dose, giving you something to verify with a meter.
For anyone starting out with re mineralizing water  after reverse osmosis, they are the right first step.
